1 Claim. 1

This invention relates to hay rakes.

It is an object of the present invention to provide a hay rake adapted to be connected to a tractor to be pulled by the same with a control device adapted to retain the rake on the ground when being pulled and adapted to release the rake to permit the same to be raised when a pull cord extending to the tractor is pulled so as to permit rake teeth to be elevated.

Other objects of the present invention are to provide a control device for a hay rake for the purpose of retaining the same in the ground position, which is of simple construction, inexpensive to manufacture, and efiicient in operation.

For a better understanding of the invention reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a top plan view of the hay rake having the control arrangement embodying the features of the present invention,

Fig. 2 is a longitudinal sectional view taken through therake on line 2-2 of Fig. 1 and with the rake teeth lowered,

Fig. 3 is a cross-sectional view taken also generally on line 2--2 of Fig. 1 showing the position of the parts when the rake teeth have been elevated,

Fig. 4 is a perspective view of the pull latch for engaging the hold down lever and which is released when it is desired to elevate the rake teeth.

Referring now to the figures, It! represents a transversely extending frame member to which there is connected to extend forwardly thereof a U-shaped member II. Extending forwardly from the transverse member I and over the U-shaped member II is an angle piece I2 on which there is pivotally connected a latch lever I3 having a pull cord I4 adapted to extend forwardly for connection with the tractor so as to be accessible to the operator of the tractor at times when a lifting lever I5 is to be operated to elevate rake teeth I6 carried on a transverse piece I1 which is pivotally connected to brackets I8 on the transverse piece Ill. The lever I5 has extensions I9 and I9a thereon which are connected by a chain 2I' to the upper end of lever I3 at a location thereon as indicated at 22. The lifting lever I5 is pivotally connected at I5a to a bracket 12a on the angle pin I2. The lifting lever I5 has a curved arm 23 which extends upwardly from the pivot I5a and then over the piece I1 for operative connection with a bracket 24 on the underside of the piece I1 by means of the lever 23a carried by the bracket 24. A roller 24a carried by the upper end of the lever 23a engages the arm 23 to permit easy operation of the two in relation to each other. A hand arm 25 extends upwardly from its connection at 25a with the piece I1 to provide means for lifting the rake teeth by hand.

Pivoted on the angle piece I2 at -26 is a hold down lever 21 with which the forward end of a projection 28 of latch lever I3 engages. A link 29 extends from the rear end of the lever 21 which connects with the hand arm 25. When the rake teeth I6 are lowered as shown in Fig. 2 the lever 21 will be retained in its forwardly extended position and the rake teeth I6 will be held down.

As the cord I4 is pulled and the rake teeth I6 are to be raised by the lever I5, the hold down lever 21 is released so that the rake teeth I6 will be made free so that they may be elevated or raised. As the pull cord I4 is released the lever I3 will be returned to its vertical position by a tension spring 3| connected between the forward end of the piece I2 and the lower end of the lever I3. Stop pin 32 limits the pivotal movement of the lever I3 by its engagement with the bottom edge of the piece I2. At the same time the pull cord is released to lower the rake teeth I6, the hold down lever 21 will pivot forwardly to locate itself under the projection 28. Any upward movement of the rake teeth l6 during the raking operation will accordingly be resisted by the latch lever I3.

While various changes may be made in the detail construction it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.

I claim:

A hay rake comprising a transversely extending frame piece, a U-shaped member connected to the transversely extending frame piece and extending forwardly thereof, a second transverse member pivotally connected to the first member, rake teeth carried on the second transverse member, so that as the second transverse member is pivoted the rake teeth will be extended between raised and lowered position, a forwardly extending angle piece connected at its rear end to said frame piece and extending over said U-shaped member and fixed to said U-shaped member adjacent the forward end of said angle piece, a hold-down lever pivotally connected to said angle piece intermediate of said frame piece and said U-shaped member, a lifting lever pivoted on the transversely extending frame piece to pivot the transversely extending member whereby to raise the rake teeth, a link connected between the second transverse member and the lever so that the hold down lever willbe operated as the rake teeth are raised and lowered, a vertically-extending latch lever pivoted on the forwardly extending angle piece extending between the transversely extending frame piece and the forwardly extending U-shaped member, said lever having a pull cord thereon adapted to be extended forwardly for connection with a tractor, said latch lever having a projection adapted to engage the hold down lever when the rake teeth are in their lowered position, and a chain same upon the supporting frame.
